CONCRETE TILE FOR BUILDING CONSTRUCTION.

in Concrete Tiles for Building Construc-..

tion, of which the following is a specification.

My invention relates to improvements in signed especially for use inbuilding walls, partitions, ceilings, etc. of building structures.

The primary object of the invention is the provision of a building-tileof concrete for the construction of walls, which will be comparativelyinexpensive of production and in the cost of material. By theutilization of the building-tiles a wall may be erected with greaterrapidity than customary, and with much facility, and by the equipment ofmy special securing devices, the liability of cracking or breaking thetile is reduced to a minimum. The walls, in addition to being erectedwith facility, may also be dismantled with equal facility, withoutmarring or destroying the tiles, and the same may be used a second timewhen desired.

My invention consists in certain novel features of constructionandcombinations and arrangements of parts as hereinafter described andclaimed.

In the .accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention constructed acording to the bestmode I have so far devised for the practical application a of theprinciples.

In the drawings: Figure 1 shows a wall, partly completed, and inperspective, built according to, and embodying the novel features of myinvention. Fig. 2 is an enlarged detail perspective view of a tile builtaccording to my invention. Fig. 3 is a detail perspective view showingframe work upon which the concrete tile is built. Fig. t is a verticaltransverse sectional view through the metallic frame of a tile. Fig. 5is an enlarged view showing an additional form of sleeve by which thetiles are bolted to the frame upright.

In the preferred embodiment of my invention I employ concrete tiles thatare made of suitable and customary material,

and molded in a machine for the purpose,

and of uniform size and shape. These tiles are built upon a metallicframe made of channel iron designated as a. whole by the numeral 2. Therectangular frame includes an end and bottom bar 2, an end and top bars3-3 which provide a tongue and groove connection (see Fig. 4). bars ofthe frame a wire mesh 4 is secured and at suitable locations on theframe, preferably at the four corners thereof, I provide a sleeve orferrule 5. These ferrules are fixed in suitable manner to the frame bars2 or 3 and extend transversely of the frame with their endsprojecting-beyond the two sides of the frame. These ferrules ac- Betweenthe four i commodate securing bolts 8 which, by means eliminate the holeand make a flush and smooth surface over the bolt head. In Fig. 5,another form of sleeve is indicated at 10, and this sleeve is embeddedin the concrete tile 7 and has a pair of lugs 11 projectingdiametrically from the sleeve to hold the sleeve against turning in theconcrete after the latter has dried.

In the structure that is illustrated as in course of erection in Fig. 1,the outerwall of a building is shown and the tiles are attnched to theuprights 8 by thebolts. As shown in Fig.4, it will be seen that theframe bars 2 provide a concave channel ing may be plastered or cementedup to around two sides of the tile, and it will be I pipe sections andare held securely in the metallic frame as shown in Fig. 3, but in someinstances it may be necessary to employ the sleeve in a position whereit is inconvenient or undesirable tolattach itto they metallic frame andin such case the sleeve with its lugs 11 is employed. By the use of thissleeve 10 the tile may be fastened or secured by the bolt 6 as desired,and the lugs 11 which are securely embedded in the con- 10 cl'etematerial prevent turning of the sleeves. In the process of erecting awall according to my invention, the first or lowest course of tile arelaid, and in Fig. 1 it will be noted that each alternate tile isattached to a stud- 1 ding. The intermediate tiles are held in placebythe interlocking joints. The tile,

' with its sleeve, embedded therein, is located in proper position, anda hole is bored in the studding in alinement with the sleeve so that thebolt may be passed throughthe sleeve and hole. The 'nut is then appliedat the end of the bolt and the bolt head is drawn tight against themouth ,or head of the sleeve. It will be noted that the strain ofattaching the bolt to the studding is taken up entirely between the bolthead and sleeve head at one end of the sleeve, and at the other end thesleeve is in direct contact with the studding. This arran ement preventsany strain on the -concrete ti e,'an d therefore eliminates thepossibility of crackingor breaking the tile.

Ir some mstanoes the bolt may be screwed home in the studding and thenut eliminated if desired.

From the above description taken in connection with the drawings, it isevident that I have provided a desirable instrumentality for performingthe functions set forth as the objects and purposes of my invention.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. The combination in a concrete tile formed on an open metallic framecomprising side and end bars with outer concave faces, and a wire screenlocated'in the frame, 4

of a sleeve extending transversely through the tile and formed withintegral diametrically arranged securing lugs. l

2. A concrete buildin tile comprising an open rectangular metallic framehaving one end and one side barformed of channel iron with the groovedface outward, and one end and one side bar of similar formation but ofsmaller dimension, wire mesh on the frame, and fastening sleeves formedwith integral lugs embedded in the concrete.

Intestimony whereof I afiix my signature in presence of two witnesses.
